GPS Jammer is designed to disrupt GPS Tracking signal from any device that might be emitting it within 10~30m around the jammer. It covers all 5 GPS L1 L2 L3 L4 L5 frequencies and it is impossible to track your movements with any GPS device or phone that might be attached to you or your car. You become invisible for GPS the moment you turn the jammer on. Protect your privacy and freedom of movement and avoid being followed or spied on. Keep on jamming with our jammers.
